TB2 supports the eight bits of digital input and outputs. These can be configured as either
inputs or outputs. The inputs can be referenced to the board ground and 3.3VDC supply
that are located on the terminal block. Inputs can be simple switch contacts, or other
solid state sensors such as optical and infrared sensors. Outputs can either sink (current
drives into the board) or source (takes current from the board) outputs. It is usually
preferable to sink current into a device, rather than sourcing it. For turning on simple
devices such as LED’s, they can be connected directly (with a resistor of course) to the
terminal block digital output and the power connection. For activating larger devices
such as relays, you will want to use a transistor or FET driver, as they can switch the higher
current that is required for those devices.
Configuration
There are two jumper blocks on the assembly and are only monitored when the board is
powered up. In the event the XBee module will not respond due to mis-configuration, or
an unknown configuration, placing a shorting block across the 'RESET' block will send the
factory reset command to the XBee and reset all the parameters. Shorting the CFG
block, will temporarily force the DL value to be a value of 0xFFFF and a MY=0x00. This
provides a communications link that can be reserved to be a configuration address only
within a system, and allows the host to send configuration commands to the XBee. See
the command instruction below for further information.
Optional Connectors
There are a number of optional connection points that can support various
communications interfaces :
Operation
When the module is first powered up, the LED will turn on as it reads several registers from
the XBee module, and transmit them over the Zigbee RF link. If a host is setup with the
proper settings to communicate with the module, the following data will be displayed
which provides the current addressing information. If the module cannot communicate
with the XBee, the LED will begin to flash rapidly indicating an error condition.

how the XBee module is configured.

that mounts on these pads is a Samtec RSM-110-02-S-S or equivalent. The mating
connector on the target board would be a Samtec TMS-110-53-SM-S or
equivalent.
